Ontario School Bus Stopping Rules: What Drivers Need to Know
The first days of school bring school buses back onto Niagara roads in large numbers. For drivers, the safest approach is to understand the signal sequence before you encounter it in traffic.

Amber lights mean the bus is preparing to stop
When a school bus activates its overhead amber lights, it is warning that the bus is slowing to pick up or drop off passengers. Drivers approaching from behind or from the opposite direction should slow down and prepare to stop, except that drivers on the opposite side of a divided road with a median are not required to stop for the bus.
Red lights and the stop arm mean stop
When the bus is stopped with overhead red lights flashing or the stop arm activated, stopping is mandatory under Ontario law.
On a road without a median, drivers travelling in both directions must stop. If you are approaching from behind the bus, stop at least 20 metres away. If you are approaching from the front, stop at a safe distance so children can get on or off and cross the road safely.
On a roadway divided by a physical median, traffic approaching from the opposite direction does not have to stop. Vehicles travelling in the same direction as the bus still must stop.
When can you start moving again?
Do not move just because you think the last child has crossed. Ontario guidance says drivers should wait until the bus begins moving, the overhead red lights stop flashing and the stop arm is no longer activated.
The penalties are significant
Ontario currently lists a first-offence penalty of $400 to $2,000 and six demerit points for illegally passing a stopped school bus with its red lights flashing or stop arm activated. Subsequent offences can result in fines from $1,000 to $4,000, six demerit points and possible jail time of up to six months.
School-bus stop-arm camera evidence can also be used to charge the registered owner of a vehicle.
Why the 20-metre distance matters
The space behind a school bus gives the driver and children room to move safely and improves visibility. Children may cross in front of the bus, and a driver following too closely can make it harder to see them.
Common mistakes to avoid
- Trying to pass before the red lights turn off.
- Assuming a multi-lane road means traffic in the opposite direction can continue; the key question is whether there is a physical median.
- Stopping too close behind the bus.
- Treating amber lights as permission to accelerate past.
- Looking only at the bus and not scanning for children near the roadway.
Niagara drivers should expect extra school-zone attention this week
Niagara Regional Police Service is running Project Safe Start from September 8-11, 2026, with officers focusing on school zones during key school travel periods.
The best reason to follow the rules is not enforcement. It is the child who may step into the roadway believing every driver has stopped.
